A generalization of Secret Sharing Scheme on the Basis of Recovering Algorithm, K-RA

Masao KASAHARA

Abstract: Extensive studies have been made of the Secret Sharing Scheme(SSS). In this paper new classes of SSS, referred to as K-SSS, $\rm{K_I}$-SSS, $\rm{K_{I\hspace{-.1em}I}}$-SSS and $\tilde{{\rm K}}$-SSS
are presented on the basis of recovering algorithm, K-RA. As an application, we shall also present a method for the recovering of secret informations learned only by heart, based on a particular class of K-SSS, $\rm{K_I}$-SSS.
